Description: Returns the probability from the inverse gaussian cumulative distribution function evaluated at x.
Syntax: pr_inverse_gaussian(x, Mean, Phi)
x is the value for which the distribution is evaluated.
Mean is the arithmetic mean of the distribution.
Phi is the parameter value.
Remarks:
x, Mean and Phi must be numerical and >= 0.
All parameter values can include:
Numerical values
Standard operands (+, -, *, /)
Predefined mathematical functions (exp, log, sin, etc.)
